Removing a color out of parameter?

you click the Parameter box when you're in the effect editor and then select all the parameters that the effect should have, i.e. C,M,R,G,B

In the original effect I have red, blue, green,magenta, cyan, yellow are listed in the Parameter box. But when you I click on the parameter box I get Saturation, hue, color mode, blue, red, green, amber, and a whole bunch of color adjust. I can't magenta, or cyan? So if I pick red, green, blue I get just those color no magenta, cyan??

ah, when you click the parameter box the CIA will show all parameters that currently exist in your show. if there are no Cyan, Magenta (and Yellow that you don't want anyway) that would mean that there are currently no CMY fixtures patched.
